NEETChemistryCoordination CompoundsMCQ+4 / −1

Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).

Assertion (A) : The metal carbon bond in metal carbonyls possesses both σ\sigmaσ and π\piπ character.

Reason (R) : The ligand to metal bond is a π\piπ bond and metal to ligand bond is a σ\sigmaσ bond.

In the light of the above statements, choose the most appropriate answer from the options given below.

  1. A
    (A) is not correct but (R) is correct
  2. B
    Both (A) and (R) are correct and (R) is the correct explanation of (A)
